Students line up for janitor's autograph

When it came time to sign yearbooks, student at one Illinois elementary school were after one signature — the janitor's.

Second graders at Alan Shepard Elementary School lined up to their yearbooks signed by Steve Weidner, who's been a custodian there for 15 years.

The photo of him with the entire class anxiously waiting for his ink was posted on Reddit Friday morning and quickly went viral. It's been viewed more than 3 million times.

The school's principal told WGN-TV Weidner is a rockstar with the students for a good reason.

"He pays attention to the kids... he knows who they are. The kids know if anything happens, Mr. Steve is going to take care of it."

A Redditor commented on the thread, "I think it's awesome an employee with no obligation to be a part of these children's lives has made such an impact they're willing to wait in line just for his signature...What a guy."

Weidner says that it was a pleasure to sign the student's books. He also said on his own Facebook, quote, "This picture is not about me! It's about the children of Alan Shepard school. My signature to me or anybody else is just that a 'signature'. But to those kids it's more than a name on paper."
